[MacPorts-announce] Prebuilt archives available for El Capitan

[Ryan Schmidt]

The MacPorts project is pleased to announce that prebuilt archives for
OS X 10.11 El Capitan are now available for many ports, and will be
used automatically when installing. These join our existing prebuilt
archives for OS X 10.6, 10.8, 10.9 and 10.10. (The building of binaries
for OS X 10.7 is temporarily suspended but will resume.)

A prebuilt archive cannot always be used, for a number of reasons:

 * Our archives are built only for the default prefix (/opt/local), so
   if MacPorts is installed in a custom prefix, it will not download
   them. This also applies to applications_dir (/Applications/MacPorts)
   and frameworks_dir (${prefix}/Library/Frameworks).
 * We only build archives for the default variants of each port.
 * Some ports have a license that does not allow for distribution of
   binaries, or have a license that conflicts with the license of a
   dependency in a way that prevents such distribution.
 * Some ports do not indicate their license, so we do not distribute
   archives of those ports.
